Title:
Lots of stuttering/crackling in guest sound
Status in QEMU:
Expired
Bug description:
When listening to music (e.g. with VLC) or watching Youtube on the
guest, there's lots of stuttering and crackling in the sound.
Tested with the following QEMU start commands:
qemu-system-x86_64 -enable-kvm -m 6G -cpu host -smp 3 -cdrom
./linux/kubuntu-20.04-desktop-amd64.iso -boot d -vga virtio -soundhw
hda -display sdl,gl=on
qemu-system-x86_64 -enable-kvm -m 6G -cpu host -smp 3 -cdrom
./linux/kubuntu-20.04-desktop-amd64.iso -boot d -vga qxl -soundhw hda
-display sdl
qemu-system-x86_64 -enable-kvm -m 6G -cpu host -smp 3 -cdrom
./linux/kubuntu-20.04-desktop-amd64.iso -boot d -vga qxl -soundhw hda
-display gtk
If I use the following command (QXL graphics, "remote" access via SPICE over
unix socket), stuttering is not completely gone but MUCH less annoying:
qemu-system-x86_64 -enable-kvm -m 6G -cpu host -smp 3 -cdrom
./linux/kubuntu-20.04-desktop-amd64.iso -boot d -soundhw hda -vga qxl
-device virtio-serial-pci -device
virtserialport,chardev=spicechannel0,name=com.redhat.spice.0 -chardev
spicevmc,id=spicechannel0,name=vdagent -spice
unix,addr=/tmp/vm_spice.socket,disable-ticketing
and this command for accessing the VM:
remote-viewer spice+unix:///tmp/vm_spice.socket
Guest: Kubuntu 20.04 64-bit (live), but occurs with many other as well
Host: Arch Linux, with KDE desktop
CPU: Intel Xeon E3-1230v2 (4 cores + hyperthreading)
RAM: 16 GB
GPU: Nvidia GTX 980 Ti
